Tombstone Tuesday - A tale of two Helens...

I've run into an issue when researching my grandmother.  See if you can figure it out from these pics:

The Helen Meadows on the first stone is my grandmother.  The Helen Meadows on the second stone is the lady my grandfather married after my grandmother passed.  Needless to say, it's thrown a wrench into my research.  For example, I can't find my grandmother's death record.  The "other Helen" keeps popping up.  It looks like I need to roll up my sleeves, get out my magnifying glass and do some digging!
